Replace utxrm(8) by utx(8).
At first, I added a utility called utxrm(8) to remove stale entries from the user accounting database. It seems there are cases in which we need to perform different operations on the database as well. Simply rename utxrm(8) to utx(8) and place the old code under the "rm" command.
In addition to "rm", this tool supports "boot" and "shutdown", which are going to be used by an rc-script which I am going to commit separately.

Remove wtmpcvt(1).
The wtmpcvt(1) utility converts wtmp files to the new format used by utmpx(3). Now that HEAD has been branched to stable/9 and 9.0 is released, there is no need for it in HEAD.

Make our utmpx more like System V.
When booting the system, truncate the utx.active file, but do write the BOOT_TIME record into it afterwards. This allows one to obtain the boot time of the system as follows:
struct utmpx u1 = { .ut_type = BOOT_TIME }, *u2;
setutxent(); u2 = getutxid(&u1);
Now, the boot time is stored in u2->ut_tv, just like on Linux and other systems.
We don't open the utx.active file with O_EXLOCK. It's rather unlikely that other applications use this database at the same time and I want to prevent the possibility of deadlocks in init(8).

Add a utility, utxrm(8).
Most of the ports I broke when I imported utmpx, were simple management utilities for the utmp database, allowing you to add/remove entries manually.
Add a small tool called utxrm(8), which allows you to remove an entry from the utmpx database by hand. This is useful when a login daemon crashes or fails to remove the entry during shutdown.

mdoc: order prologue macros consistently by Dd/Dt/Os
Although groff_mdoc(7) gives another impression, this is the ordering most widely used and also required by mdocml/mandoc.

Just ignore the timestamps given to pututxline().
I've noticed many applications do a bad job at timekeeping, for several reasons:
- Applications like screen(1) don't update time records when restoring the old user login record. - Many applications only set ut_tv.tv_sec, not ut_tv.tv_usec.
This causes many problems for tools such as ac(8), which require the timestamps to be properly ordered. This is why I've decided to let the utmpx code obtain valid timestamps itself.

Perform several small cleanups to the utmpx code.
- Massively reduce BSS usage. Let futx_to_utx() dynamically allocate the structure. There is only a very small amount of applications out there that needs to use the utmpx database. Wasting 1 KB on unused structures makes little sense.
- Just let getutxid() search for matching ut_id's for any *PROCESS-type. This makes the code a bit more future-proof.
- Fix a POSIX-mistake: when reading POSIX and the OpenSolaris implementation, getutxline() must return USER_PROCESS and LOGIN_PROCESS records whose ut_lines match. When reading POSIX, it seems LOGIN_PROCESS should not use ut_line at the first place. I have reported this issue.

Add wtmpcvt(1).
This utility allows users to convert their wtmp databases to the new format. It makes no sense for users to keep their wtmp log files if they are unable to view them.
It basically copies ut_line into ut_id as well. This makes it possible for last(1) and ac(8) to match login records with their corresponding logout record.

Implement <utmpx.h>.
The utmpx interface is the standardized interface of the user accounting database. The standard only defines a subset of the functions that were present in System V-like systems.
I'd like to highlight some of the traits my implementation has:
- The standard allows the on-disk format to be different than the in-memory representation (struct utmpx). Most operating systems don't do this, but we do. This allows us to keep our ABI more stable, while giving us the opportunity to modify the on-disk format. It also allows us to use a common file format across different architectures (i.e. byte ordering).
- Our implementation of pututxline() also updates wtmp and lastlog (now called utx.log and utx.lastlogin). This means the databases are more likely to be in sync.
- Care must be taken that our implementation discard any fields that are not applicable. For example, our DEAD_PROCESS records do not hold a TTY name. Just a time stamp, a record identifier and a process identifier. It also guarantees that strings (ut_host, ut_line and ut_user) are null terminated. ut_id is obviously not null terminated, because it's not a string.
- The API and its behaviour should be conformant to POSIX, but there may be things that slightly deviate from the standard. This implementation uses separate file descriptors when writing to the log files. It also doesn't use getutxid() to search for a field to overwrite. It uses an allocation strategy similar to getutxid(), but prevents DEAD_PROCESS records from accumulating.
Make sure libulog doesn't overwrite the manpages shipped with our C library. Also keep the symbol list in Symbol.map sorted.
I'll bump __FreeBSD_version later this evening. I first want to convert everything to <utmpx.h> and get rid of <utmp.h>.
